On Friday afternoon I was at the summer party of the chair of ergonomics at the Technical University of Munich. Klaus Bengler, who took over the chair earlier this year and became professor, had in his talk 3 interesting points to take away:

  1. to assess more how much does bad ergonomics costs us (from health to missed sales)
  2. to quantify the value of ergonomics in real money in order to make it comparable with other factors in product design
  3. to include ergonomics as an integral part of the development process

From my Computer Science/HCI perspective I think (2) would be top of the list – as we have good approaches to (3) but need (2) to push it and as (1) is part of (2)… It would be great to have an argument based on economics. E.g. adding tactile feedback will costs x € and it will increase the value of the product by y € – if x>y do it – else don’t … still… Continue reading

It is about 15 years that I came across the idea of newspapers – printed in the shop where you buy them (sometime when I studied in Ulm). Today I have seen an advert for print on demand newspapers in the international newspapers kiosk in the central station in Munich. They have 850 titles from 70 countries available – as print on demand. The display copies had a decent quality – looked like A3 size color laser printouts – perhaps I can fetch a copy tomorrow.

I wonder how long it will take to move more (low volume papers, local… Continue reading

Next week is the early registration deadline for the 1st International Conference on Automotive User Interfaces and Interactive Vehicular Applications (AutomotiveUI 2009) and the poster call is still open.

This year the deadline for submitting papers to TEI 2010 is much earlier than in previous years! It is the 10th of August (and was already extended)…

Reto Wettach was in Essen so we took the opportunity to get together to flash out some ideas for a proposal – it is related to pain – in a positive sense. There is interesting and scary previous work, see [1] & [2]. For the proposal we still look for someone not from the UK and not from Germany – who has an expertise and interest in medical devices (sensors and actuators) and someone who has experience in pain and perception of pain (e.g. from the medical domain). Please let me know if you know someone who may fit the… Continue reading

Why would I write a post about a power plug? Perhaps in some years this may be so common that we do not know when the first appeared 😉 And here is my reference point for Essen, Germany.There is a German news article about these chargeing points – there are 22 in Essen and they started sometime back in Berlin (where they plan to have 500 by the end of the year).

It looks very much like an ordinary power plug and I have not figured out how it really works – e.g. How to pay? How to reserve that… Continue reading

I came across this study in computer bild – you should not cite it as it in a scientific paper as “computer bild” – is consumer paper telling people mainly which computers to buy and how to use obvious features in software 😉

Nevertheless it is interesting and gave me some ideas what navigations systems are good for and it is another example that user needs on an abstract level (e.g. as in Maslows hierarchy of needs) could be interesting to inform designs.

If you do not read German here are the results in short:

In the afternoon I gave a talk at NEC labs in Heidelberg on ubiquitous display networks. Over the last year we developed and number of ideas and prototypes of interactive public display systems. We run a lab class (Fallstudien) on pervasive computing technologies and advertising together with colleagues from marketing. In another class (Projektseminar) we investigated how to facilitate interaction between interactive surfaces (e.g. multi touch table) and mobile devices. One of the prototypes will be shown as poster at mobile HCI 2009 in Bonn. In some thesis projects we introduced the notion of mobile… Continue reading

Gilbert Beyer from Munich came to visit our lab. In Munich he is working on interesting projects that combine aspects of software engineering and human computer interaction in the group of Prof. Martin Wirsing. Gilbert participated in the pervasive computing in advertising workshop in Nara and we met there.

We discussed aspects of how to study and empirically evaluate larger and off-desktop interactive systems. Even though those systems differ significantly from desktop systems the book How to Design and Report Experiments by Andy Field and Graham J. Hole is still a good starting point.

Carting new territories is exciting… Continue reading

Meeting with other researchers that run or have run Emmy Noether research groups is very different from normal conferences and meetings. The participants are across all disciplines – from art history to zoology 😉 The meeting focuses mainly on strategic, political, personal, administrative and organizational issues when starting a research career. This year we had child care organized during the meeting and Vivien came with me to Potsdam.

On Saturday night I learned that we (our galaxy) will eventually collide with the Andromeda Galaxy (but after our sun is out fuel – so I do not worry too much). Vivien… Continue reading

On the trip to Potsdam two young women sat opposite us – discussion one-by-one the pages in the yearbook of their school. The yearbook was from a school in Berlin was from 2009 and printed in highest quality – quite professional. Their discussion had a lot of forward references (what will become of people – and how they see and present themselves now). Looking back 10, 20 or 30 years after leaving school these images and texts are very interesting… There is a real value in paper that cannot be altered – here new technologies (facebook and alike) that evolve… Continue reading

For the 1st International Conference on Automotive User Interfaces and Interactive Vehicular Applications (AutomotiveUI 2009) we got many quality submissions. The review process is now complete and we accepted 12 full papers and 10 notes for oral presentation at the conference. The list of accepted contributions is online at auto-ui.org.

As a number of people have asked if the still can submit to the program and as many of the rejected papers raise interesting aspects we decided to have Posters as a further submission category. We have a continuous submission process for poster abstracts till Sept 1st 2009. Earlier submissions… Continue reading

Friday and Saturday we came to Velen (Hotel SportSchloss Velen) to discuss mainly administrative and strategic issues – and there are plenty. The place is amazing and I was annoyed with myself for not bring my SLR… Nevertheless I took some photos with my N95.

Such meetings highlight for me that the German scientific system is undergoing a major change – with many opportunities and risks. A lot of political constraints are pushed onto the university – many seem to be just copies of other systems that are working less than perfect (e.g. bachelor/master, research evaluation, etc.). Being… Continue reading

Elektor magazine features in the current issue a DIY Segway called Elektor Wheelie. The system is build around a ATMEGA32 and has obviously a lot of mechanics. For sensing an ADXL320 (acceleration sensor) and an IDG-300 (gyro) are used. Looks like a fun project – and you have full access to the software (not sure what you really would program differently, perhaps one can tune it to get faster 😉

Perhaps it could be a platform to motive embedded programming – with clear real-time constraints, as it hurts if you fall off… Next term we are teaching digital system… Continue reading
